Title: Highly accurate light output monitor
Inventor: FUKAISHI MITSUSUKE
IPC: H01S3/131
Filed: 1998-12-10
Abstract: PROBLEM TO BE SOLVED: To provide an optical amplifier output monitoring circuit, capable of accurately receiving output signal light from an optical amplifier and highly accurately controlling the optical output level of the amplifier. SOLUTION: An optical branch 2 transmits an output signal light L2 outputted from an optical amplifier 1 and gives transmitted light to a fiber grating(FBG) 4. The FBG 4 makes the output signal light L2 to be incident from the amplifier 1, reflects signal light L3 which is a part of the signal light L2, and returns the light L3 to the branch 2. At this time, the FBG 4 transmits the residual of the output signal light L2, including spontaneous emission light (ASE). The branch 2 bifurcates the reflected signal light L3 and applies the bifurcated signal to a light receiver 3. The light receiver 3 converts the bifurcated signal light into an electrical signal and gives the electrical signal to a control circuit 5. The circuit 5 controls the optical output level of the amplifier 1, based on the electrical signal inputted from the receiver 3.

Filed: 1991-12-13
Abstract: PURPOSE:To manufacture a coiled decoration implement by laminating sheet-like wool fibers by plurality of colors, coil the laminated wool fibers and impregnate the coiled wool fibers with water to be pressed. CONSTITUTION:A sheet A is formed of wool fibers 1a, 1b and 1c having respectively three different colors and laminated in the mensioned order sequentially. Next, a roll B is obtained by coiling the sheet A from one end. If these is a kind of the wool fibers difficult to impregnate with water, soap suds are applied to the sheet A to facilitate the impregnation of the fibers with water. Hot water and water are alternately applied to the roll B and cause sufficient water to penetrate through the fibers to stick the fibers of the roll B to each other. While the fibers are impregnated with water, the roll B is pressed by a pressure plate 2 and rolled back and forth. The roll is compressed by the press to stick the fibers to each other. Thus, since the wool fibers are stuck to each other, a cylindrical decoration implement C is provide which is difficult to collapse and has durability and a spiral pattern on the section of the cylindrical implement C.

IPC: F16H63/30
Filed: 1997-12-09
Abstract: PROBLEM TO BE SOLVED: To suppress a flexible rate of a shift arm by restricting movement of a shift rod simultaneously with the completion of a shift. SOLUTION: When in association with an operation of a shift lever 1 by an operator, a sleeve 5 is moved toward a dog gear 7 and the sleeve 5 is engaged with the dog gear 7 completely, the sleeve 5 is stopped at a speed change completing position correctly. It is thus possible to surely prevent over- shift of the sleeve 5.

Title: Dimming device
Inventor: SENBA KAZUHISA
IPC: H05B41/392
Filed: 1993-12-28
Abstract: PURPOSE:To reduce a noise by providing a dividing circuit for dividing a rectangular wave signal, and lighting an illumination load by a frequency equal to an output frequency of the dividing circuit, so as to reduce a shift component of the frequency. CONSTITUTION:Voltage input from a power supply line is converted into DC power in a rectifying circuit 15, to produce an output in accordance with load voltage of an illumination load 3 by a step down chopper circuit. Then, since a step down chopper circuit output, appearing in both ends of a smoothing capacitor, is DC power, it is reversed to be changed into AC power, in a full- bridge type inverter mainly composed of transistors(Tr) 9 to 12, and supplied to the load 3. Thus, the load 3 is lighted by rectangular wave power of frequency corresponding to an operating frequency of the Tr 9 to 12. This operating frequency is generated by inputting a lighting signal, in which a dimming signal from a duty ratio variable rectangular wave signal generator 6 is converted in a dividing circuit 7, to a control circuit 8. Then by selecting dividing ratio, when the load 3 is lighted by a signal synchronized with each other, noise generation to a duty ratio part of the dimming signal is eliminated.
